Either a single lateral (or "Line"), of LeakyPipe®, laid down each row, or perhaps a line on both sides. (The latter os probably O.T.T.) All LeakyPipe lines then teed into 20mm polytube "supply" pipe, using 20-12-20mm barbed reducing tees. Ideally, feed the water supply into the middle of the polytube "manifold" and turn-on. The network will fill-up an quickly work all-at-once. (Of course, you do have to plug off the ends of the LeakyPipe and the polytube manifold). As this is a long-term cropping situation: Once you've seen it working, we would recommend that you place the LeakyPipe into the soil as this is better for the water distribution and keeps the LeakyPipe® away from husbandry operations.
